We pride ourselves on our professionalism, customer service and providing the highest level of customer satisfaction. We are your neighbors – we live here, we work here and we give back to our communities. We want to make Long Island a better place to live for generations to come through clean, efficient solar power. Let us show you how you can own your future and save money with your own solar power system. Discover the bright side of a money-saving solar system, custom-built with the industry’s best warranty and Zero Out-of-Pocket (ZOOP) costs. And trust our eight-year reputation as the number one solar company on Long Island. SUNation: Solar as it should be.

SUNation offers only high-efficiency, premium-quality solar panels with expert workmanship and installation. For the most part, solar systems of this quality require little maintenance over their lifespan, if any at all. The components we install all come with full 25-year warranties, inverters included, that protect you in the event of the slightest malfunction. SUNation installs monitoring hardware on every system that allows us and our homeowners to know when anything is wrong.

One of the most common misconceptions when purchasing a solar system is that it’s going to be expensive. In reality, over 96% of our customers experience Zero Out Of Pocket costs. While financing the cost of a system up front is the best way to realize all the savings that solar offers, SUNation offers low and no-interest loans that make going solar one of the most affordable decisions you’ll ever make.

SUNation Cares is the not-for-profit affiliate of SUNation Solar Systems, Inc. We’re proud to work with needy families to help them considerably decrease or eliminate their electric bills with a donated, fully-functioning solar system. SUNation Cares supports Long Island veterans’ charities.

Help Your Community Learn to Become Energy Efficient and Use Clean, Solar Energy!

At SUNation, our customers become a part of our family. For us, a customer referral is the highest compliment we can receive for the work we do. And, when you refer a friend, neighbor or family member you’re saving us advertising dollars. We’d rather see your family get a check than send one out for advertising.

For each person you refer to us that goes solar, we’ll send you $500 after their system is installed. When your third recommendation goes solar with SUNation, that referral fee goes up to $1,000 and you’ll continue to get $1,000 for everybody you send to us from then on. And you thought you were just saving on electricity!
